Congrats! We bought our 02 4.4 from Carmax in 2007. It was a pleasure buying from them. They actually shipped the car from another location for free.

If you got a warranty on it, I would recommend paying the $50 co-pay to take the vehicle to the BMW dealer of your choosing for warranty repairs. I like Carmax, but don't trust them enough to work on mine. They goofed a couple things up when we initially bought ours. We had them replace a headlight and they put in the light from a non-sport package and when they did an oil change, they didn't use OE oil and filters. Doesn't seem like a big deal, but it would have been bad to follow the dash indicators for the full 15,000 mile interval on a non-OE filter. Other than that, I was happy with Carmax. Good luck!
